循环流化床热解油田采油污泥的实验研究[J]

, 2011
以新疆克拉玛依油田采油污泥为对象,将煤与其混合后考察了混合物的失水情况,并采用热重分析仪和小型循环流化床热解反应器研究了混合物的热解过程及其热解效果.结果表明,与煤混合后油泥的干燥速度明显加快,干燥后的混合物90％以上粒径分布在1～6 mm范围内.混合物热解主要经历了轻质组分挥发、重组分快速热解失重和缓慢失重3个阶段.流化床热解结果表明,在600℃下热解3 min时,油 ...

倾斜角度及加热方式对脉冲热管传热性能的影响

, 2004
该文对以FC-72为工质的脉冲热管进行了实验研究，采用高速动态采集系统测量了脉冲热管的热力型脉动曲线，并获得了脉动周期，分析了加热功率及倾斜角度对脉动周期的影响。通过实验发现在倾斜角度0=0°～10°时，脉冲热管传热性能对角度极为敏感，加热段温度随着倾斜角度的增加急剧下降；当e=10°～15°时，加热段温度反而略有上升；当e=15030°时，加热段温度又缓慢下降；而当倾斜角度e=30°-90°时，加热段温度变化很小，倾角对传热性能几乎无影响。同时 ...

南海天然气水合物加热开采过程中海底稳定性研究

, 2009
利用Abaqus有限元软件，结合我国南海水合物的矿藏情况，对水合物的加热开采过程进行传热分析。首先利用热流值计算输入的总热量，再根据已分解的水合物计算水合物分解消耗的热量以及产出的天然气燃烧后产生的热量，估算在加热开采过程中的热效率(用于水合物分解的热量与输入热量之比)、能量效率(开采所得甲烷气体燃烧后放出的热量与输入热量之比)与水合物分解范围之间的关系。结果表明，当水合物分解到一定范围后，产出热量会小于输入热量，所以在实际开采过程中应控制水合物的分解范围，以保证较高的热效率 ...
